I am developing a site which seems to have some memory leak. Using RedGate Memory Profiler, I can see that the unused memory allocated to .net is quite large. From what I have read so far, it might have something to do with objects on the large object heap. Looking at the objects in the large object heap I can see that there is an array of an Linq to Umbraco entity which has a live size of 131,088 bytes but a size with children of 14,675,390 bytes (see http://screencast.com/t/BDIWdnSvbi5). Looking further into this it seems to be the Linq 2 Umbraco datacontext, which is causing this: http://screencast.com/t/XDnjJeWkAJmW. Is there someway I can prevent this behavior?
I am running 4.7.1 and caching the Linq to umbraco context as shown here http://vimeo.com/9790069
It turned out that my iis was set to not allow 32 bit applications. Allowing 32 bit applications solved the problem. Shouldn't it be possible to run umbraco on a 64-bit box?
Memory leak?
Hi,
I am developing a site which seems to have some memory leak. Using RedGate Memory Profiler, I can see that the unused memory allocated to .net is quite large. From what I have read so far, it might have something to do with objects on the large object heap. Looking at the objects in the large object heap I can see that there is an array of an Linq to Umbraco entity which has a live size of 131,088 bytes but a size with children of 14,675,390 bytes (see http://screencast.com/t/BDIWdnSvbi5). Looking further into this it seems to be the Linq 2 Umbraco datacontext, which is causing this: http://screencast.com/t/XDnjJeWkAJmW. Is there someway I can prevent this behavior?

Hmm I haven't used Linq to Umbraco for a while, but I heard it has some performance problems. Might be better to use something else. You can find some alternatives in this topic: http://our.umbraco.org/forum/developers/api-questions/18933-Query-multiple-websites

Hi Jeroen
thanks for the reply. As far as I can see it is only Linq2Umbraco that offers strongly-typed objects of the alternatives mentioned?

Well with Razor you can also use Strongly Typed objects if you want. Have a look at this: http://razordatatypemodels.codeplex.com/

Hi Jeroen,
It turned out that my iis was set to not allow 32 bit applications. Allowing 32 bit applications solved the problem. Shouldn't it be possible to run umbraco on a 64-bit box?
